  • Eight winter wheat varieties were tested to study the varietal differences on yield and the other characteristics at four different treatments with two different photoperiod and two different temperature levels. In heading date, Changkwang and Parker exhibited the moot sensitive responses to short day length, but Yecora 70. Suweon 169 and Bezostaya were insensitive in general. Culm length was greatly increased at short day length in Bezootaya while Yukseong 3 expressed same responses under low temperature condition. However, little variation of culm length was observed in Yecora 70 regardless the day length. Blueboy, Changkwang and Yecora 70 exhibited the minimal variations in culm length due to the temperature treatment. High yieldings were produced in Blueboy, Suweon 169 and Parker under short day condition, but Parker, Yecora 70. Yukseong 3 and Study produced high yields due to the influences of low temperature. Yield increase was primarily due to the increased number of spikes per plant and number of spikes per plant and 1, 000 grain weight under the low temperature conditions.

  • The new garden chrysanthemum (Dendranthema grandiflorum Ramat.) cultivar 'Nuri Ball' was developed at Yesan Chrysanthemum Experiment Station of Chungcheongnam-do Agricultural Research and Extension Services in 2011. 'Nuri Ball' was bred through a cross between the '02-145-01' line as the female parent with yellow flower color and '02-04-32' as the male plant with white flower color in 2004. Three years of adaptation trials were conducted from 2006 to 2009 under natural conditions. This study compared the external shape type with that of 'White Miri' and conducted ploidy and RAPD (Random amplified polymorphic DNA) marker analyses. These tests showed that 'Nuri Ball' cultivar has its own characteristics compared with the control 'White Miri'. 'Nuri Ball' was a shrub type variety with semi-double flowers of 4.0 cm in width with white petals. It could produce 1025.2 flowers per plant in autumn. Compared with the control 'White Miri', 'Nuri Ball' was similar in terms of shape and color of flowers, but was different in flower size and number. The natural flowering time of 'Nuri Ball' was late September. It had very vigorous growth and an early budding plant. 'Nuri Ball' was demonstrated to be a new cultivar based on ploidy test and RAPD analysis. 'Nuri Ball' is intended for use as a bed chrysanthemum and expected to contribute to farm incomes in landscaping.

  • A new cultivar of oak mushroom Lentinula edodes 'Jadam' was bred from monokaryotic strains of 'Hwadam-18' and 'GMLE36295-22'. The optimum temperature for mycelial growth of 'Jadam' on potato dextrose agar was 22-25℃. Total cultivation period of the new cultivar, from inoculation to its first harvest, was 122-124 days, shorter to that of the control cultivar 'Hwadam'. Total yield of 'Jadam' was 623.8 g per 3 kg substrate, and is higher than that of 'Hwadam' (455.2 g). In the fruiting body of the new cultivar, the stipe was shorter and thinner than those of 'Hwadam'. A farmhouse field test showed that the period of mycelial growth and browning was shorter than that of control cultivar 'L808'. The total yield for 2 flush was 543.3 g for 'Jadam'. It was similar to the 585.3 g of the control cultivar. Therefore, the new cultivar 'Jadam' could be a substitute for 'L808' in the field of farms.

  • 값싼 수입산 참깨가 우리의 식탁을 점령한지 오래되었지만, 여전히 국내산 참깨를 선호하는 국민들의 관심도 높다. 국내에서 참깨재배를 원활히 하기 위하여 참깨품종 육성연구가 지속적으로 이루어지고 있지만 아직까지 수량성이나 재배안정성, 품질 면에서 소비자 및 생산자 모두를 만족시킬 수 있는 품종개발이 부족했다. 이에 국립식량과학원에서 이러한 단점을 개선한 신품종 '유미'를 개발했다.
